Harold Melvin & the Blue Notes were one of the most popular Philly soul groups of the 1970s. Though ostensibly led by Melvin, Teddy Pendergrass was the most influential member of the group. They were signed to Gamble & Huff's Philadelphia International label. Though they had several hits from 1972 to 1975, they dried up after the departure of Pendergrass. The group continued touring, however, until Melvin died in 1997.
